I've discarded Nibbler as unplayable initially, at least on my RPi. Only played a bit on my new PC for the last day couple of days, definitely an improvement in terms of responsiveness but still one of the most infuriating games I've ever-played, control wise. I don't know how you guys do it, kudos for the big scores
Though still way short of these billion+ man vs snake scores... I'm going slightly crazy after 1 hour of this game and can't even begin to imagine ~2 days of non-stop play needed to reach that kind of score.
